Summary:Bidirectional sun-induced chlorophyll fluorescence was quantified by the three dimensional radiative transfer model (FLiES). The results suggested that the canopy scale chlorophyll fluorescence was highly variable with respect to the observation angles. The contribution of multiple scattering depends on the wavelength and a larger scattering contribution was found in the near infrared. Thus, the relationship between satellite-observed SIF and photosynthesis varies with sun and observation geometries. These results suggest that the SIFs observed from satellites are necessary to standardize by applying the correction of bi-directional effect.
